Rachel Riley has turned the end of her book photoshoot into a baby bump one, sharing the beautiful photos with fans and followers on Instagram.

The Countdown star - who is expecting her second child with Pasha Kovalev - could be seen cradling her bump in a series of black and white and coloured photos.

"When, at the end of a successful photo shoot for the cover of my new maths book #atsixesandsevens, the fabulous @rayburmiston asked if I wanted a quick bump shot the answer was hell yeah! 5 minutes extra and pics to treasure forever - thanks Ray 😍 Not sure which will be out first between the book and the baby but the book's release date is 28th October and both are cooking nicely ☺️👶🏼📚."

Fans loved the photos and inundated Rachel with warm wishes and kind words. "You look so wonderful - what a joy," one fan commented.

"You are glowing!" another added.

She and former Strictly Come Dancing pro Pasha are already parents to daughter Maven, who they welcomed to the world in December 2019. They tied the knot in Las Vegas in 2019, after meeting on the BBC dance contest back in 2013.

Meanwhile, Rachel's maths book for adults is aimed at helping "anyone and everyone who ever thought maths was ‘above’ them." It offers an accessible introduction into how numbers work and why we shouldn't be afraid of them. At Sixes and Sevens is ready to pre-order on Amazon now.
